Give a pane's body its own Text holding the cursor, selections, mode and undo

acme keeps what edits a text in its Text (dat.h:171-190) and the window
holds a body and a tag of that type. The cursor, the selections, the modal
state and the edit-buffer undo move off Pane into Text.zig, Pane holds
them as its body, and the edit and normal-mode operations take the Text
they edit. Nothing changes in behaviour; this is the step that lets the
tag become a second Text.
